What Does Noritz Error Code 90 Mean?
Noritz error code 90 is indicative of a maintenance code. Pretty much every 90 error code signals some kind of maintenance issue.
These error codes pop up in the wake of improper maintenance or if you’ve performed no maintenance on your Noritz tankless water heater to date. In some areas, maintenance is more crucial.
In regions with hard water, like Los Angeles County, yearly maintenance is key to preventing early breakdown and extending the lifespan of your Noritz tankless water heater. The minerals and other contaminants in hard water cause scale build-up with the heat exchanger of your Noritz tankless water heater.
When scale build-up gets to a critical point, it causes the heat exchanger to work harder to reach the set temperature, leading to early breakdowns and potentially damaging the heat exchanger to the point of replacement.
So, How Do You Fix Noritz Error Code 90?
The good news about error code 90 is that it’s a relatively easy fix. Because Noritz error code 90 is a maintenance code, all you need to do is call a professional out to your home to perform maintenance and make sure everything is working properly.
If your technician doesn’t discover any issues stemming from improper maintenance, they’ll go ahead and run internal and external maintenance on your Noritz tankless water heater.
The process shouldn’t take very long, and the error code will be resolved once the technician wraps their procedure. Despite the easy fix, if Noritz error code 90 pops up on your tankless water heater, you should think about changing the way you maintain your Noritz tankless water heater. If this issue repeats, you can bet that you’re doing damage to your investment, and it won’t provide you with the maximum possible return.
Going through Another Issue?
It’s entirely likely that you’ll run into another error code throughout the lifespan of your Noritz tankless water heater. While these machines are some of the best on the market, they’re still mechanical and can experience hiccups from time to time.
Other error codes can be just as simple to fix, while others may require more intensive repair. For instance, Noritz error code 12 occurs when there is an issue with the gas pressure or airflow that causes a lack of flame. In this case, it could be something as simple as debris stuck in the exhaust or intake.
Regardless of the error code that pops up on your Noritz tankless water heater, the best course of action is to call a technician to resolve the issue. While many homeowners prefer the DIY approach, some error codes are complex and involve working with combustion components, meaning it’s risky business to go it alone.
